expiration algorithm not working

[saylor09]

Using JBossCache 3.1.0GA, I'm attempting to set expiration times per added node. Based on the documentation, I have thus far:


DefaultCacheFactory factory = new DefaultCacheFactory();
Cache cache = factory.createCache();

Fqn fqn = Fqn.fromString("/streams");
Node streams = cache.getRoot().addChild(fqn);

Node child = streams.addChild(Fqn.fromString("/node1"));
child.put(ExpirationAlgorithmConfig.EXPIRATION_KEY, 100);

Fqn nf = Fqn.fromString("/streams/node1");
Thread.currentThread().sleep(2000);
System.out.println(cache.getNode(nf));

Thread.currentThread().sleep(2000);
System.out.println(cache.getNode(nf));
....

The node never gets evicted. Should I expect it to? I've also tried setting the ExpirationAlogrithm in the config:


ExpirationAlgorithmConfig algorithm = new ExpirationAlgorithmConfig();
EvictionRegionConfig evictionRegionConfig = new EvictionRegionConfig(fqn, algorithm);
cache.getRegion(fqn, true).setEvictionRegionConfig(evictionRegionConfig);


But this has no effect. I've searched for anything with EXPIRATION_KEY but can't find any other related posts. Does this feature work?

Thank you,

Scott

See my post here:

I think you've got the same problem....

Read docu: "The expiration time is indicated using the org.jboss.cache.Node.put() method, using a String key expiration and the absolute time as a java.lang.Long object, with a value indicated as milliseconds past midnight January 1st, 1970 UTC (the same relative time as provided by java.lang.System.currentTimeMillis() )."

The key has to be absolute time, whereas you're giving it a relative time:

child.put(ExpirationAlgorithmConfig.EXPIRATION_KEY, 100);

And @mjdinsmore, it's not the same issue that you have in the other forum entry

Yup. I realized that later on. I set absolute time and it still doesn't work. I tried infinispan and it works fine there.
